AER-F: Compact external rotor kit for highest force density at slow travel speeds

The AER series external rotor torque motors are specially designed for high torque at very low speeds. The AER-F series is maintenance and wear-free due to its brushless design. The arrangement of the magnets and the coil design have been further developed to make optimum use of the advantages of the external rotor principle. Minimal cogging ensures good synchronous running characteristics at low speeds and thus enables good control ability for highest precision. These characteristics make the external rotor torque motors ideal as a drive solution for CNC machining and ensure excellent process results.

• Stator/Rotor kit
• Approx. 50% higher torque than internal rotor
• Watercooling for high torque
• Diameter from 225 / 285 / 335
• Max. 600VDC

The RBE Series from Kollmorgen is a proven platform offering many years of direct drive motor solutions in various industries such as defence, semiconductor, machine tools, industrial automation, medical, and robotics. The frameless configuration is provided as a rotor and stator component that are integrated directly with the load where the same bearings which support the load also support the motor. This configuration eliminates shaft, bearings, endbells, and couplings offering reduced volume, weight, and complexity.
As the saying goes, these motors are ‘oldies but goodies’ and continue to be viable solutions where relatively high torque and low speed, pancake type motor configurations are required.
